  • At least a portion of said liner of the cap may comprise elasticity.
  • the active insert device of the cap may comprise a reactant that when triggered to a reaction, releases a gas that increases a pressure of said expansion chamber and causes said portion to elastically expand from an unstretched condition to rupture and produce an aperture through which said gas may be released and elastically returns to said unstretched condition when said pressure equilibrates with a pressure outside said expansion chamber, and wherein said aperture closes as said portion elastically returns toward said unstretched condition.
  • the expansion chamber of the cap may comprise a recess in a location selected from the group consisting of said liner and said surface of said cap.
  • the active insert device of the cap may be disposed in said recess.
  • the surface of the cap may comprise a section that may be transparent to light energy, wherein said active insert device may comprise a reactant and responds to said light energy to trigger said reactant to a reaction in said expansion chamber.

  5. Behälter (920) nach einem vorhergehenden Anspruch, wobei der Durchlass eine Öffnung umfasst, durch die das Gas freigesetzt wird, wobei der Teil bei zunehmendem Druck auseinanderklafft und die Öffnung bildet, die sich wieder schließt, wenn der Teil in den ungedehnten Zustand zurückkehrt.
  6. Behälter (920) nach einem vorhergehenden Anspruch, wobei die externe Energiequelle elektromagnetische Energie bereitstellt, wobei die aktive Einsatzvorrichtung einen Induktor umfasst, der auf die elektromagnetische Energie unter Auslösen der Reaktion anspricht.
  7. Behälter (920) nach einem vorhergehenden Anspruch, wobei die externe Energiequelle Lichtenergie bereitstellt, wobei die aktive Einsatzvorrichtung auf die Lichtenergie unter Auslösen der Reaktion anspricht.
  8. Verfahren zur Unterdrucksetzung eines Behälters (920), der eine abgeschlossene Kammer, eine Halsmündung und einen auf die Halsmündung aufgebrachten Verschluss umfasst, wobei das Verfahren umfasst:
    Einbringen einer Innenauskleidung zwischen eine Innenfläche des Verschlusses und die Halsmündung, so dass ein hermetisch abgedichteter Expansionsraum zwischen der Innenfläche und der Innenauskleidung gebildet wird, wobei die Innenauskleidung (501), die den Expansionsraum bildet, mindestens einen Teil mit Elastizität umfasst, und
    Einleiten einer Reaktion im Expansionsraum, so dass Gas produziert wird, das den Teil der Innenauskleidung (501), der den Expansionsraum bildet, von einem ungedehnten Zustand derart ausdehnt, dass sich ein Durchlass (502) öffnet, durch den das Gas in den Behälter freigesetzt wird, wobei der Teil elastisch in den ungedehnten Zustand zurückkehrt, wenn sich der Druck an einen Druck in dem Behälter angleicht, und wobei sich die Öffnung schließt, während der Teil elastisch wieder in den ungedehnten Zustand zurückkehrt.
